An object of the invention is to provide a metal parting bead, andimproved means employed therewith, for weather proofing windows of metalor wood construction. An

` improvement and advantage of my device lies in the provision of meanswhereby an effective seal is formed between the sash and frame, eventhough there be considerable side or end play between these members.

Another object of my invent-ion is to provide means to check side playin window sashes, and to eliminate the rattling noise caused by wind. A

A further object of my invention is to provide a weather strip whichpermits the sash to be easily removed and replaced without distorting orremoving any member of the strip, from its secured position in thewindow assembly.

A still further object and advantage is attained in the ease andfacility with which the weather `proofing of my invention can beinstalled, since it has been found that an ordinary mechanic is able toequip a window with my device in considerably less time than is requiredwith any of the prevailing types. ther objects and advantages willappear from the following detailed description of a single executionalembodiment of my invention and the accompanying drawings thereof, inwhich Fig. 1 shows a horizontal sectional view through a portion of awindow frame and upper and lower sashes, to which my parting member andweather strip has been applied; Fig. 2 is a perspective, phantom view,the purpose of which is to illustrate the position of the biasing memberhereinafter described; Fig. 3, a fragmentary perspective view, shows ametal parting bead of prefererd form, and paired weather proofingmembers in operable disposition and Fig. 4 is a sectional elevationtaken on line 4-4 of Fig. 1, and shows a preferred method of securingthe parting bead into position.

Referring nowto Fig. 1, upper and lower sashes 5 and 6 are adapted toslide vertically in their respective guideways formed by the pulleystile member 7, the outer bead 8, and the inner bead 9. The pulley stile7, is provided with a. groove or channel which con- Cil stitutes a seatfor a spacing member or parting bead. In the ordinary windowconstruction, the parting bead is of standard width and usuallycomprises a strip of wood, rectangular in cross section, which runs fromthe bottom to the top frame members.

I prefer, however, to provide a parting bead 11, of sheet metal. Zinc orcopper is well adapted for this purpose, although any non-rusting metalor rust-resisting metal may well be used. My parting bead comprises,essentially, a hollow rectangular member, one wall of which has anarrow, longitudinal opening 12, cut centrally therethrough. The partingbead is adapted to be positioned in the channel 10 with the slotted walloutermost, and preferably secured by means of angulate members such as13, at the ends thereof. These members, fastened as by screws 14, intothe top and bottom frame member, provide a simple expedient for holdingthe parting bead into the groove, and permit the bead to be easily andquickly removed.

My weather strip comprises, essentially, a sealing member 15, whichcooperates, in slidable engagement with member 16, to form a seal in themanner illustrated in Fig. 3. The members 16, which for convenience willbe termed slidable members, are fastened to the stiles of the sash, andpreferably extend the full length of these members. A plan view of thesliding members reveals a straight portion 17, a bend 18, and curvedportion 19. The portion 17 is provided with perforations 20 atsuitableintervals alongl its length, and nails or screws, indicated at 21,extend through these apertures and serve to fasten the sliding membersto the sash. The marginal portion is preferably rebent, as shown,thereby protecting the heads of the securing elements and producing asliding surface of relatively small area.

The sealing member 15, preferably of channeled construction and formedalso of sheet metal, includes a corrugated flange 22, a web 23, and aportion 24 which, by preference, is curved to conform with portion 19 ofthe sliding member 16. It is obvious that the mating portions 19 and 24may be of any suitable form, but I prefer to make them arcuate,

and thus improve the seal formed therebetween. The corrugated flange 22is adapted to be disposed within the parting bead and the web 23 extendsthrough the opening 12, in the manner shown. A resilient member 25,preferably in the form of a semi-elliptical spring, is positionedbetween the front wall of the parting bead and the flange 22 andfrictionally retained by means of the corrugations, and permits thesealing member to be moved outwardly of the parting bead, aga-inst thebiasing action of the spring. By reason of the spring and semi-floatingposition of the sealin member, this latter element is constantly he d incontact with the sliding member, and the seal is maintained in spite ofsidewise movement or irregularities of the frame. In windowconstructions, a condition is often encountered where from wear or otherreasons, the sash stiles are not parallel to the ulley stiles. It istherefore advisable to m e provision to compensate for this misalignmentby permitting, as in the present example, the members to assume avariable angular position, through a range of a few degrees, withrespect to the parting bead, which is usually secured in parallelrelation to the pulley stiles. Otherwise expressed, the springs 25 areso disposed as to permit dissimilar distance relations to exist, alongand between portions of the members 15 and the parting bead.

Although sealing members only slightly in excess of sash length would besuiicient, I prefer to extend these elements the full lengt-h of thewindow frame, and provide springs at suitable spacings along their lenh. B. this arrangement, the Weather proofing is efective regardless ofthe position of the sash, and all noise caused by the rattling of aloose sash is eliminated.

In installing the Weather stripping of my invention, the members 16 arenailed or screwed to the stiles in the manner shown. The upper or outersash 5 is put in the trame and retained by means of the parting bead.The parting bead, with sealing members and springs assembled therein, isplaced in the groove 10, it being necessary to draw the member 15,outwardly against the action of the springs so as to permit engagementwith the sliding member. In like manner, the lower or inside sash ispositioned and secured by means of the inside bead 9.

It will thus be obvious to those skilled in the art, that my deviceaffords many advantages over prevailing forms of weather stripping. Manyof these employ a metal strip cooperating with a channel cut into thesash or rame and the cutting and fitting of the channel and stripmember, demand a consideration amount of the time of a skilled mechanic.

While the aboveV description and the accompanying drawings illustrate apreferred embodiment of my device, I do not wish to limit it to thespecilic construction and arrangement of parts shown, as variousmodiiications and deviations may be made without departing from the fullspirit and scope of my invention.
